insecticidal efficacy for up to 5 weeks against fleas (Ctenocephalides felis
The product has shown acaricidal efficacy against infestations one
week after application; however, no acaricidal efficacy was seen immediately after treatment
or two weeks after treatment. If ticks of this species are present when the product is applied,
all the ticks may not be killed within the first 48 hours but they will be killed within a week.
External use only.
Administer by topical application to the skin 1 pipette of 0.5 ml per animal.
Thermoformed pipettes
1. Clear Spot-on must be applied at 2 points, at the base of the back of the cat’s head, and
between the shoulder blades. If the cat is wearing a collar, remove it first so that it does not
restrict application.
2. To open, hold pipette upright and snap off the tip.

3. Part your cat’s coat until the skin is visible. Place the tip of the pipette directly against
the skin and squeeze gently. Apply approximately half of the pipette at the back of the
cat’s neck and half between the cat’s shoulders. Squeeze the pipette several times to
ensure dosing is complete. Avoid applying onto the fur and do not rub into the skin, as
this will reduce the product’s performance.
Polypropylene pipettes
Remove the pipette from the blister packaging. Hold the pipette in an upright position and
snap off the top section of the cap, thereby opening the pipette.
Part the pet’s coat until the skin is visible. Place the tip of the pipette directly against the
bared skin and squeeze gently. Empty approximately half the contents at two points along
the cat’s back, preferably at the base of the head and between the shoulder blades. Squeeze
the pipette several times to ensure dosing is complete. Avoid applying the solution onto the
fur and do not rub into the skin.
Application of the solution as directed minimises the possibility that the animal will lick the
solution off.
Care should be taken to avoid excessive wetting of the hair with the product since this will
cause a sticky appearance of hairs at the treatment spot. However, should this occur, it will
usually disappear within 24-48 hours post application. There is little evidence available from
studies with this product in cats; however, from studies in dogs, crystals may be seen on the
hair and slight scaling may occur within 24-48 hours after application.
Treatment schedule:
The minimum interval between two treatments is 4 weeks. In some cases longer intervals
between treatments may be appropriate. For advice speak to your veterinary surgeon.

to the solvents in the product.
Among the extremely rare suspected adverse reactions, short duration skin reactions at the
application site (scaly skin, hair loss at the application site, skin irritation, itching and
reddening) and general skin irritation or hair loss have been reported after use. Rarely,
excessive drooling / salivation, and reversible nervous signs (e.g. excitability, depression)
or vomiting have been observed after use.
fall off the host within 48 hours after infestation without having had a blood meal as a rule
but an attachment of single ticks after treatment cannot be excluded. A transmission of
infectious diseases by ticks cannot thus be excluded. Once dead, ticks will often drop off the
animal, but any remaining ticks may easily be removed by a gentle pull.
Fleas from pets often infest the animal's basket, bedding and regular resting areas such as
carpets and soft furnishings which should be treated, in case of massive infestation and at
the beginning of the control measures, with a suitable insecticide and vacuumed regularly.
Avoid frequent swimming or shampooing the animal because the maintenance of
effectiveness of the product in these cases has not been tested.
For optimum control of flea problems in a multi-pet household, all dogs and cats in the
household should be treated with a suitable insecticide.
Special precautions for use in animals
- Avoid contact with the animal’s eyes. In the case of accidental eye contact, immediately
and thoroughly flush the eyes with water.
Do not apply the product on wounds or damaged skin.
It is important to make sure that the product is applied to an area where the animal cannot
lick it off, and to make sure that animals do not lick each other following treatment.
The safety of the product has not been investigated in studies where overdose or repeated
dosing were used due to the well-known safety profile of the active substance and the other
ingredients.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
- This product can cause mucous membrane and eye irritation. Therefore, contact
between the product and the mouth or eyes should be avoided.
- In the case of accidental eye contact, immediately and thoroughly flush the eyes with
water. If eye irritation persists seek medical advice and show the package leaflet or the label
to the physician.
- Avoid contents coming into contact with the fingers. If this occurs, wash hands with soap
and water. Wash hands after use.
- Do not smoke, drink or eat during application.
People with a known hypersensitivity to fipronil or any of the other ingredients should avoid
contact with the veterinary medicinal product. Treated animals should not be handled until
the application site is dry, and children should not be allowed to play with treated animals
until the application site is dry. It is therefore recommended that animals are not treated
during the day, but should be treated during the early evening, and that recently treated
animals should not be allowed to sleep with owners, especially children.
